In organic chemistry, benzyl is the term for the anion C6H5CH2-, which can be obtained formally by deprotonation of toluene. The benzyl functional group is sometimes abbreviated "Bn", not to be confused with "Bz", which is short for the benzoyl group. For example, benzyl alcohol can be abbreviated to BnOH.
Additional recommended knowledge
In substituent nomenclature, benzyl and phenyl are commonly confused. Benzyl can be seen as a phenyl attached to a CH2 before attaching to the parent compound.
Benzyl protective groups
Two common methods for benzyl ether protection:
One study  employs a benzyl pyridinium salt as a benzyl donor for alcohols:
The solvent is trifluoromethylbenzene and magnesium oxide is an acid scavenger. The reaction type for this conversion is believed to be SN1 based on the detection of trace amounts of Friedel-Crafts reaction sideproducts with toluene as a solvent.
